These wedges will effectually prevent creeping or other movement of thedetachable member. The}; need not be pisccd at very close iniervoissince the entire strain is upon the wedgo and not upon tho com--parotiveiy wed: bolt. In removing the tire, the bolts 6 will bewithdrawn, which will allow the Wedges to be shaken from their seats,and a few light blows with a hammer will loosen the rnembr 2, when ow,tire will be free to be removed. It will be thus seen that freezing orsticking; of the tire cannot so readily occur on rims nrmdo in themanner above descrilccci.
